Abstract:
The disclosed materials, methods, and apparatus, provide novel ultra-high temperature materials (UHTM) in fibrous forms/structures; such “fibrous materials” can take various forms, such as individual filaments, short-shaped fiber, tows, ropes, wools, textiles, lattices, nano/microstructures, mesostructured materials, and sponge-like materials. At least four important classes of UHTM materials are disclosed in this invention: (1) carbon, doped-carbon and carbon alloy materials, (2) materials within the boron-carbon-nitride-X system, (3) materials within the silicon-carbon-nitride-X system, and (4) highly-refractory materials within the tantalum-hafnium-carbon-nitride-X and tantalum-hafnium-carbon-boron-nitride-X system. All of these material classes offer compounds/mixtures that melt or sublime at temperatures above 1800° C.—and in some cases are among the highest melting point materials known (exceeding 3000° C.). In many embodiments, the synthesis/fabrication is from gaseous, solid, semi-solid, liquid, critical, and supercritical precursor mixtures using one or more low molar mass precursor(s), in combination with one or more high molar mass precursor(s). Methods for controlling the growth, composition, and structures of UHTM materials through control of the thermal diffusion region are disclosed.
Abstract:
The present disclosure primarily relates to interceptor unmanned aerial systems and methods for countering Unmanned Aerial Systems (UAS), although the inventions disclosed herein are useful for capture of any aerial object. The system utilizes a rigid effector frame, an effector attached directly to the frame, and at least two propulsion elements connected to the effector frame, and is configured to intercept and disable threat UAS. The disclosed systems can be oriented to any virtually any angle to maximize the chances of intercept.
Abstract:
A compactor comprising a compression chamber, ram means for compressing a slug of material, expulsion means for expelling the slug from the chamber and control means for maintaining continuous sequential operation.
Abstract:
A waste compactor includes a horizontally extending compacting chamber with a cantilevered open-ended front section closed by an openable first gate and a chute communicating with a rear upper feed opening. A ram is hydraulically motivated along the chamber between advanced, retracted and intermediate positions. An electrical network controls the ram when the first gate is closed and material sensed in the chute ro reciprocate the ram between intermediate and retract positions until the hydraulic pressure exceeds an adjustable value at the intermediate position and to reciprocate the ram between the retracted position and a point rearwardly of the intermediate position when hydraulic pressure exceeds a second predetermined value. Upon opening of the first gate the ram can be fully advanced.
Abstract:
A card package production system (100) for producing card packages (115) composed of printed paper carriers (113) with matching cards (128) attached to the carriers (113) selectively outputs the card packages through a card package multi-directional distribution module (136) having a carrier transport with a primary carrier transport path extending between a package inlet (262) and a primary package outlet (144) for transporting the card packages along the primary carrier transport path. A movable stacker gate assembly (214, Fig. 7) mounted for movement between a stacking position (Fig. 26). In the stacker position, the card packages are inserted laterally through a laterally facing inlet (145) of a stacker (146) in two stages with successive pairs of card packages (115. 115') being kept in an interleaved state.

A movable stacker gate assembly (280) mounted for movement between a stacking position in which the card packages are guided by the stacker gate assembly (280) off the primary carrier transport path and into the stacker (164) and a nonstacking position in which the carriers are allowed to continue past the stacker input. The gate is selectively controlled to direct carriers preselected for mailing to the primary outlet (144) and carriers preselected for stacking to the stacker assembly (146).
Abstract:
A single sheet printer (21) is adapted to receive continuous carrier forms for printing by a burster module (16) for separating continuous printable stock (24) into separate bursted sheets which are fed to the printer transport mechanism (12) in lieu of the single sheet storage module.
Abstract:
A system and process for polishing and radiusing a microhole (52). A liquid slurry with particular rheological properties accelerates as it flows through the microhole (52) to abrade the edge of the microhole (52). When the flow rate reaches a target flow rate the process stops and the microhole (52) is properly calibrated.
Abstract:
The disclosed methods and apparatus improve the fabrication of solid fibers and microstructures. In many embodiments, the fabrication is from gaseous, solid, semi-solid, liquid, critical, and supercritical mixtures using one or more low molar mass precursor(s), in combination with one or more high molar mass precursor(s). The methods and systems generally employ the thermal diffusion/Soret effect to concentrate the low molar mass precursor at a reaction zone, where the presence of the high molar mass precursor contributes to this concentration, and may also contribute to the reaction and insulate the reaction zone, thereby achieving higher fiber growth rates and/or reduced energy/heat expenditures together with reduced homogeneous nucleation. In some embodiments, the invention also relates to the permanent or semi-permanent recording and/or reading of information on or within fabricated fibers and microstructures. In some embodiments, the invention also relates to the fabrication of certain functionally-shaped fibers and microstructures. In some embodiments, the invention may also utilize laser beam profiling to enhance fiber and microstructure fabrication.
